NBG-318S User’s Guide

The following list, which is not exhaustive, illustrates the standards supported in the NBG-
318S.

Bandwidth Management 

You can efficiently manage traffic on your network by reserving 

bandwidth and giving priority to certain types of traffic and/or to particular 

computers.

Time and Date

Get the current time and date from an external server when you turn on 

your NBG-318S. You can also set the time manually. These dates and 

times are then used in logs.

Port Forwarding

If you have a server (mail or web server for example) on your network, 

then use this feature to let people access it from the Internet.

DHCP (Dynamic Host 

Configuration Protocol)

Use this feature to have the NBG-318S assign IP addresses, an IP 

default gateway and DNS servers to computers on your network.

Dynamic DNS Support

With Dynamic DNS (Domain Name System) support, you can use a 

fixed URL, www.zyxel.com for example, with a dynamic IP address. You 

must register for this service with a Dynamic DNS service provider.

IP Multicast

IP Multicast is used to send traffic to a specific group of computers. The 

NBG-318S supports versions 1 and 2 of IGMP (Internet Group 

Management Protocol) used to join multicast groups (see RFC 2236).

IP Alias

IP Alias allows you to subdivide a physical network into logical networks 

over the same Ethernet interface with the NBG-318S itself as the 

gateway for each subnet.

Logging and Tracing

Use packet tracing and logs for troubleshooting. You can send logs from 

the NBG-318S to an external UNIX syslog server.

PPPoE

PPPoE mimics a dial-up over Ethernet Internet access connection.

PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of 

data through a Virtual Private Network (VPN). The NBG-318S supports 

one PPTP connection at a time.

Universal Plug and Play 

(UPnP)

The NBG-318S can communicate with other UPnP enabled devices in a 

network.
